Radon Mitigation in a Longmeadow, MA Townhouse: Reducing Radon from 6.1 to 1.5 pCi/L
If you own a townhouse in Longmeadow, MA, you may assume radon mitigation is more difficult because of shared walls, HOA requirements, and limited options for vent pipe placement. Fortunately, that's not the case. Our team recently completed a successful radon mitigation system installation in a middle-unit townhouse in Longmeadow, lowering the home's radon level from 6.1 pCi/L to just 1.5 pCi/L while maintaining the clean exterior appearance required by the homeowners association.
The Challenge: Radon in a Middle-Unit Townhouse
Unlike single-family homes, middle-unit townhouses present unique challenges for radon mitigation. With neighboring homes on both sides, there are fewer routing options for vent piping, and homeowners often need to comply with strict HOA guidelines regarding the appearance of the building.
In this Longmeadow townhouse, our goal was to install an effective system without compromising the home's curb appeal or violating HOA expectations.
Using the Existing Sump Pump as the Suction Point
To maximize the efficiency of the system, we utilized the home's existing sump pump pit as the sub-slab suction point. This is often an excellent option because the sump pit already provides access beneath the concrete slab, allowing us to create strong negative pressure under the foundation without adding unnecessary penetrations.
After sealing the sump properly and installing a professionally designed active soil depressurization system, we ensured the system would continuously draw radon gas safely from beneath the home and vent it above the roofline.
A Clean Installation Designed for HOA Approval
One of the homeowner's biggest concerns was preserving the appearance of the townhouse exterior. We carefully planned the vent pipe routing to create the cleanest and most discreet installation possible.
Our technicians completed the exterior up-run with neat, professional pipe placement that blends with the home while meeting both industry standards and the visual expectations of the homeowners association. We believe a radon system should not only perform exceptionally well—it should also complement the appearance of your home.
Outstanding Results
The post-mitigation radon test confirmed the effectiveness of the system:
- Initial Radon Level: 6.1 pCi/L
- Final Radon Level: 1.5 pCi/L
This represents a significant reduction in radon exposure, bringing the home well below the EPA action level of 4.0 pCi/L and providing the homeowners with greater peace of mind.

What Our Customers Say About Us
"Extremely Prompt and Professional! Responded quickly to the request, set an appointment for the very next day. Arrived on-time and texted me 30 min ahead of time as I requested. Upon evaluating existing passive equipment, the job was lower than the initial estimate provided. Highly recommended!"
"Spoke directly to Ed, the owner, who gave me a quote on the spot after a few questions. Had an appt within a week of calling, at my convenience. Installer was pleasant and professional. Called a couple of other companies who either never called back or who decided my oddly laid out basement ( part full, part crawl, part addition with dirt floor) was something they didn't want to deal with. Ed was confident they could do the job, and did!"
"Very prompt and even my realtor said she had never seen one done so neatly. Less than two hours to complete. Would definitely use NE Radon again."
"NE Radon Doctors were amazing. They did a wonderful job, very fast and super clean. Cannot be happier. Also, our radon levels dropped significantly. Thanks a lot!"
"Timely, courteous, meticulous, all around a good experience."
"This was not my first home sale, I was selling the house, buyer did a radon test - NE radon doctors offered a competitive rate and was quick to help - but the gentleman that showed up to do the install was a real professional, represented the company well. I will sell other homes and every home in the valley has radon, I know I will use them again."
